Sampling was done at six stations between September 2017 Accepted: 16 January 2020 to July 2018.

The other most important publications on Iranian aquatic Station 6: Sendegan Spring, substrate: muddy; 1739 m beetles are: Atamehr and Alaei [1], Mousavi et al. [15], Dar- a.s.l.; near Sendegan, 60 Km from the town of Lordegan; ilmaz et al. [2], Samin et al. [17], and Van Vondel et al., [21]. 3115’35”N 5117’00” E; 29. IV. 2018. Apart from a study conducted by Heydarnejad [7] on aquat- ic coleopteran of Choghakhor in 2010, no other study has not been done in Chaharmahal and Bakhtiari province so far. Thus, this study aimed to study aquatic coleopteran faunas of Borujen and Lordegan, Chaharmahl and Bakh- tiari province, Iran. 2. Materials and Description of Sampling Sta- tion

Chaharmahl and Bakhtiari, one of the 31 , lies in the southwestern part of the country. Its capital is Shahrekord surrounded by the famous Zakros mountains. Due to the high mountainous nature, which is in the path of the wet winds of the Mediterranean sys- tems, which makes these systems rise and discharge, the province has relatively good rainfall to the extent that this region, with only one percent of Iran's construction, is ten percent the country has water resources (Figure Figure 1. Location of Chaharmahl & Bakhtiari province 1). Between September 2017 to July 2018 a field trip within Iran to Borujen and Lordegan (as two main towns of the province) was carried out by M.Taher. During this trip 6 sampling stations were examined that are listed below and presented on the map (Figure 2). The results are based on the study of 51 adults of Dytiscidae, 20 adults of Haliplidae, 17 adults of Noteridae, and 4 adults of Hydrophilidae. Identification of samples was based on morphological characteristics such as external taxonom- ic characters and external male genitalia with appropri- ate entomological reference books and authors [5,6,13,22]. All samples were deposited in the Zoological Museum, Shahrekord University (ZMSU).
